2017 Updates to PubMed and MeSH

Here are some highlights of what’s new with the PubMed search interface and the Medical Subject Headings (MeSH) Browser in 2017:

  • PubMed’s new “Best Match” Sort Option

If you have searched PubMed this year, you may have noticed a prompt (displayed only once per session by the search engine) to try out PubMed’s “Best Match” Sort Option. The Relevance sort has been renamed “Best Match” so that the PubMed Sort Options now include: Most Recent, Publication Date, First Author, Last Author, Journal, Title and Best Match.

From PubMed Help:

“The retrieved by best match sort order for search results is based on an algorithm that analyzes each PubMed citation that includes the search terms. For each search query, “weight” is calculated for citations depending on how many search terms are found and in which fields they are found. In addition, recently-published articles are given a somewhat higher weight for sorting.”

Every year, the National Library of Medicine (NLMupdates the MeSH browser to better accommodate the current literature being indexed in the MEDLINE database. Among the 2017 MeSH Headings newly added to the MeSH Browser, one that will no doubt be useful for cancer research in particular is the:

New MeSH Descriptor: Margins of Excision

From the MeSH Browser:

“The edges of tissue removed in a surgery for assessment of the effectiveness of a surgical procedure in achieving the local control of a neoplasm and the adequacy of tumor removal. When the margin is negative or not involved by tumor (e.g., CANCER) it suggests all of the tumor has been removed by the surgery.

A 2017 qualifier update was also made this year, when “three qualifiers (radiography, radionuclide imaging, and ultrasonography) were replaced by a new qualifier diagnostic imaging.”

New Qualifier: Diagnostic Imaging

From the MeSH Browser:

“diagnostic imaging [Subheading]

New Parent Company for Endnote

If you have visited the Endnote.com company website recently, you may have noticed a change in their branding.  What used to be the the Intellectual Property and Science business of Thomson Reuters, which was also responsible for Endnote, has now been launched as an independent company called ClarivateTM Analytics.

Other than the absence of the Thomson Reuters logo, there do not yet appear to be any changes at the new company that are affecting the Endnote citation management software program. Clarivate Analytics has, however, already released a new version of Endnote (X8) that is not yet available via our MSK subscription but will likely be coming to us in 2017. Endnote X8 promises some advanced sharing functionality that will surely interest our community of MSK Endnote users. Feel free to contact the MSK Library with any questions or concerns.

Wishing everyone a happy and productive 2017!

Accessing Online News Sources via the MSK Library

The MSK Library’s “eJournals” collections include more than just scholarly journals. Popular news sources such as the New York Times, the Wall Street Journal, Crain’s Health Pulse, and The Cancer Letter are also included amongst our periodical subscriptions.

There are multiple ways to explore and access the MSK Library’s subscription resources:

One way is by going to the MSK Library homepage  and searching the library’s online Tri-Cat catalog for the title of interest.  For example, searching for The Cancer Letter, will lead you to its record in the Tri-Cat catalog. Within the catalog record, you will find a link to “Access full-text from MSK” that you can click on to be taken into the full-text subscription.

Another way of getting to the full-text content is by going to the library homepage and clicking on the “eJournals” link (4th item along the blue menu bar). If you do a Title search here, you will be presented with some hyperlinked options that you can follow to get to the full-text source of interest. Please note that occasionally the hyperlinked title also includes instructions for registering for an account or signing in to the resource (possibly after clicking on “Password Lookup” to obtain the institution’s sign in username and password for that particular resources), whatever the case may be.
